Something smells fishy

On the other hand, some reviews did advise the fishy smell is definitely there but not offensive at all. Therefore, this may not be an issue for you depending on your tolerance for odors.

CON’S

PRO’S

CON’S

Capsules are made with gelatin from the fish tilapia, some users have reported negative reactions to this

#7 Jarrow Formulas Krill Oil

Phospholipids a plenty

With roughly half of the 1200 mg serving size being phospholipids (650mg) this product is sure to be absorbed easily by your body so that you can reap the health benefits. Most brands will generally have less than half the serving size of phospholipids. However Jarrow’s didn’t cut any corners here.

Astaxanthin levels are relatively low

They may not have skimped on the phospholipids, but unfortunately this product only carries just over 0.1mg of astaxanthin. This antioxidant protects your krill oil from losing its potency. Therefore, it would have been good to see it in higher levels in a product such as this one that hits the mark on all other aspects.

PRO’S

CON’S

Only 0.115 mg astaxanthin per serving

#8 Purity Labs Pure Antarctic Krill Oil

Contains omega-6

Similar to omega-3, omega-6 fatty acids have been known to assist with issues like ADHD, diabetic neuropathy, allergies, and rheumatoid arthritis as well as lowering bad cholesterol. Purity Labs have included an omega-6 count of 40mg per serving which is a beneficial added bonus.

The omega-6 to omega-3 ratio in krill is about 1:12. Unfortunately, omega-3 levels have been lowered a little in this product with around 60mg EPA and 40mg DHA per serving.

Comparatively, this is a bit less than other brands. Generally, omega-6 is found in a lot of fast foods and meats which are generally abundant in everyone’s diet. Therefore, increasing it in this supplement and removing some omega-3 may have been a little counterproductive depending on your specific health needs.

PRO’S

CON’S

Only 200 mg of phospholipids per capsule

Less EPA and DHA than other brands

#9 Onnit Krill Oil

What is krill oil?

Krill are tiny, shrimp-looking crustaceans that live in the oceans of the world. At only about 10mm-20mm in size, they are food for larger sea mammals like penguins, whales, and seals.

Generally, the krill used to extract krill oil are harvested from the freezing, pristine Antarctic waters. Harvesting them from here, coupled with krill having a short lifespan, means there’s much less chance they will be carrying mercury and toxins inside their tiny bodies. This is just one of the advantages that krill oil has over fish oil.

Euphausia superba is the species of krill mostly used for krill oil. Krill all over the world make up one of the largest biomasses on this earth at an estimated 600 million tons. So, as this research article mentions, krill are an ecologically sustainable resource.

What can a krill oil supplement do for my health?

Krill oil is a supplement that provides your body with omega-3 fatty acids. Krill possess such high amounts of these acids because they feed on algae, which is a natural source of omega-3.

Your body is unable to produce these fatty acids on its own, but they are essential for human health. Therefore, unless you’re consuming the equivalent of eight ounces of fish every week, which would give you the recommended dose of omega-3 fatty acids, then it may be a good idea to think about introducing a supplement to your life.

What does Krill Oil Contain?

The health benefits of krill oil boil down to the following key components:

Highly concentrated Polyunsaturated Omega-3 fatty acids

Polyunsaturated omega-3 fatty acids, or POFAs, assist with the prevention and treatment of heart disease as well as inflammation and other related health issues.

Antioxidants in the form of carotenoids

Astaxanthin, a type of carotenoid antioxidant, provides can help fight off oxidative stress that can help prevent liver damage. In addition, it can provide protection against ultraviolet light and UV-induced skin damage.

Vitamin A

Vitamin A plays a crucial role in reproduction, bone growth, and immune system health. It is also essential to healthy vision and good skin.

Vitamin E

Vitamin E is a powerful antioxidant that protects skin cells from damage and helps to lower cholesterol

Phosphatidylcholine

Astaxanthin, a type of carotenoid antioxidant, provides can help fight off oxidative stress that can help prevent liver damage. In addition, it can provide protection against ultraviolet light and UV-induced skin damage.

So what is omega-3?

There are three types of omega-3 fatty acids that include docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and the less beneficial alpha-linolenic acid. These acids help with everything from mental health to fighting chronic inflammation. Most importantly however, omega-3 can lower your cholesterol and risk of heart disease.

The great thing about krill oil is that these fatty acids are stored as phospholipids, as opposed to fish oil where they’re stored as triglycerides (more on this later). Phospholipids are thought to be more easily absorbed by the human body, however more studies need to be conducted on this before it can be confirmed.

Here’s a few of the benefits some of the best krill oil supplements can provide:

1. Easier to absorb than fish oil

As mentioned above, krill oil actually comes in the form of a phospholipid which is a molecule that is made up of two fatty acids, a phosphate group and one glycerol molecule.

All this basically means that these lipids like to line themselves up neatly with your cell membranes and therefore can be absorbed easily.

Although more research is needed to confirm this fact, the triglycerides that fish oil’s fatty acids are stored in may not be as easily absorbed into the body as the fatty acids from krill oil.

2. Reduces and prevents inflammation

Inflammation is important because it’s our body’s way of fighting off infections and healing wounds. However, not all inflammation is necessary. And when it becomes chronic inflammation, you might need a helping hand to calm things down. The omega-3 fatty acids in krill oil is able to be converted into eicosanoids, or signalling molecules that tell your body to release anti-inflammatory chemicals known as prostaglandins.

3. Can help fight mental disorders

DHA makes up around 60% of your total brain tissue. A krill oil supplement can help to lubricate it and allow greater cognitive function. In addition, the other fatty acids will help with submitting the electrical pulses that your brain uses to communicate with the rest of your body.

Keeping your brain in top health with consistent omega-3 fatty acid intake can help with the following disorders:

Schizophrenia

ADHD

Anxiety

Depression

Alzheimer’s

4. Lowers cholesterol to improve cardiovascular health

The heart health benefits of krill oil are perhaps the most widely known. Omega-3 acids are known to assist with lowering bad cholesterol levels, increasing good cholesterol, and reducing triglycerides in your body

5. Reduces PMS Symptoms

Because omega-3 reduces inflammation, keeps hormones in balance and combats fatigue and mood-related issues, taking a daily krill oil supplement may help you around that dreaded time of the month if you suffer from bad PMS.

6. Contains the antioxidant astaxanthin

Astaxanthin is an antioxidant found in krill oil that isn’t generally found in fish oil. It protects EPA and DHA from oxidizing and losing its potency. As the levels are so low, you won’t get the normal antioxidant benefits from it. However, it will help your krill oil’s fatty acids to be protected and optimized when working throughout your body.

7. Fights autoimmune diseases

Autoimmune diseases are those that occur when your immune system starts attacking normal cells because it mistakes them for nasty, harmful ones. Diseases like lupus, rheumatoid arthritis, type 1 diabetes, multiple sclerosis, and more are often very hard to treat. However, omega-3 fatty acids have been linked to alleviating their symptoms.

8. Liver repair

Research suggests phosphatidylcholines found in Krill Oil, may have a healing effect on liver cells, and thus encourage liver repair.

9. Reduces cancer cells

Research shows that some cancer cells will respond to omega-3 by slowing and even reversing their growth. This result has been seen mostly with hormonal cancers and colorectal cancer. Because of these findings, consistent krill oil intake may help to prevent certain cancers.

10. Fetal brain development

For pregnant women, krill oil may be beneficial for two reasons. First of all, there is very little risk of heavy metal contamination. This is due to krill being at the bottom of the food chain. Therefore, the krill don’t have the time to gather pollutants compared to other marine sources. Hence, it is reasonably safe to use during pregnancy.

Secondly, the high concentration of Omega-3 fatty acids are extremely beneficial for good fetal brain development and early childhood brain development.

Please remember however that expectant mothers should always consult their doctor before taking any supplements while pregnant.

11. Skin care and wound healing

The high potency of omega-3 fatty acids present in krill oil may have an anti-inflammatory and antioxidant effect on the skin. This can help to reduce acne and scarring and improve the healing process of wounds.

Also, since it is an oil, krill oil can benefit hair and skin by providing an all-around glow. The presence of vitamins A and E also help in the improvement of hair and skin conditions and act as antioxidants alongside the carotenoid astaxanthin.

12. Weight Loss

The omega-3 fatty acids present in krill oil is thought to speed up metabolism and fat burning, as well as reduce appetite.

These are only the findings so far on krill oil. However, after more testing on krill oil and its benefits, it is a wonder what other amazing properties it possesses.

Krill oil v fish oil

Whether to use krill oil or fish oil is one of the most commonly asked questions and has sparked a series of debates worldwide. These conversations have pointed to krill oil as being superior for the following reasons

Bioavailable

The most unique thing about krill oil is its natural composition. It contains omega-3 fatty acids which are attached to phospholipids. This means that your body can readily absorb it unlike the triglycerides in fish oil which have to be broken down in your gut.

Krill oil is therefore more effective, as it allows the body to absorb up to 15 times more omega-3 than fish oil. This also allows for a lower dosage, which can ultimately save you money.

High Antioxidant levels

Krill oil’s antioxidant levels are 48 times higher than fish oil. This is mainly due to the high potency of antioxidant astaxanthin which formulates a unique bond with omega-3 fats.

Environmentally sustainable

Krill harvesting is carefully regulated. It is considered one of the most environmentally sustainable practices on the planet.

Only 1 to 2% of krill biomass is harvested each year. This takes some of the guilt away of consuming it.

Contamination free

As krill is at the bottom of the food chain it feeds on phytoplankton as opposed to contaminated fish. This makes it pure and uncontaminated. This is in contrast to fish oil which is prone to mercury and other toxins.

No fishy aftertaste

Unlike fish oil, which gives you a terrible fishy aftertaste particularly after burping, krill oil has less of the fishy taste. Krill oil also comes in smaller-sized gel capsules, which makes them easier to swallow.

Tips and tricks for purchasing the best krill oil supplement

Where do my krill come from?

The best krill oil comes from the southern most part of the earth. For the most toxin-free krill oil, make sure they’re being harvested from the pristine waters of Antarctica and in an ecologically sustainable way.

Omega-3 content

Omega-3 fatty acids are the main reason you’re going to be consuming krill oil. Therefore, be sure to get a supplement that has the highest levels possible within the daily recommendation of around 1200mg and never exceeding 2000mg krill oil daily.

The best brands will list exactly how much EPA and DHA they have in them. Also pay attention to how much astaxanthin is listed. The higher the astaxanthin levels, the better your omega-3 fatty acids will be protected in your body and in their capsules before you’ve purchased them.

Serving size

Pick a product as close to 1200mg per serving that you can find. If this is all in one capsule, it is even better since it will be easier to remember to take. However, most brands will recommend two capsules a day, so be sure the serving size measures up to the daily recommendation.

Phospholipids

As mentioned above, the most important difference between krill oil and fish oil is that krill oil is delivered into your body in the form of phospholipids. Be sure to pick a product with a high level of phospholipids to ensure the most efficient absorption into your body.

Steer clear of toxins, chemicals and additives

Be on the lookout for brands that bulk out their krill oil capsules with additives, allergens or fillers – steer clear of them at all costs. And if you can, do a little research into the brand’s extraction and production processes and side effects to make sure they don’t expose the supplement to any kind of harmful toxins or chemicals.
